To all when it may concern.

Be it known that I, FRANCIS M. JACKSON, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Window-Front Constructions, of which the following is a specification.

This invention relates to ventilating window front constructions and my object is to produce a construction of this character whereby window lights of different thicknesses may be easily and reliably secured in position and by which air may be caused to circulate against the inner face of the glass to prevent frosting of the same under certain weather conditions.

With this general object in view and others as hereinafter appear, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in

Figure 1, is an outer face view of a window front construction embodying my invention. Fig. ,2, is an enlarged sectional perspective view of a part of the same. Fig. 3, is a vertical section taken on the line lII ill of Fig. 2, but on a smaller scale. Fig. 4, i a horizontal section taken on the line IV V of Fig. 3. Fig. 5, is a-horizontal section on an enlarged/seal taken on the dotted line V. of Fig. 1. Fig. is a section on the line Vl-Vl of Fig. 5. Fig. 7, is a horizontal section of that part of the construction uniting the adjacent vertical edges of glass panes eisposed at an angle to each other. Fig. 8, is a section on the line VIII--VIII of Fig. 7.

In the said drawings, an angle bar is arranged so that its arm 1 is arranged horizontally and its arm ,2 vertically, and the latter provided at its upper edge with an arm 3 projecting outwardly and downwardly and equipped in its outer edge with equi-spaccd apertures 4.

An angle bar inverted with respect to the first-named angle bar has its arm 5 arranged vertically and its arm 6 projecting upwardly and inwardly by preference, the window-' lights 7 being arranged between the adjacent edges of arms 3 and 6. The arm 5 rests upon arm 1, and is provided in its lower edge with equi-spaced apertures 8. Y

9 indicates a series of angle brackets arranged at suitableintervals in the passage formed by and between the angle bars and secured at their lower ends to arm 1 and at theiropposite'ends to arm 2, at lb, or in any other suitable manner.

11 indicate screw bolts extending through the outer angle bar 5-6 and the alined bracket 9 for the purpose of adjusting said angle bar 5.6 toward or from angle arm 2 to accommodate window lights of different thickness, rubber or equivalent cushions 12 being interposed between the edge of the glass and the brackets 9 to protect the former from chipping while supported by the brackets.

13 indicates a slide plate fitting against the inner side of wall 5 of the outer angle bar,

- provided with longitudinal slots is engaging the bolts H and held by the nuts. l5 also ongaging said bolts, snugly against arm 5 of the said outer angle bar, the said slide plate having apertures 16 in its lower edge rorrcspmuling to the apertures H, and adapted to register with the latter when air is to be admitted to the space between the angle bars. For the purpose of adjusting the slide plate to throw its apertures 16 in or out of engagement with apertures 8, it is provided with a vertically extending slot 17 receiving the disk 18 provided eccentrically with the outwardly projecting hub 19 journaled in a circular hole 20 in arm 5 of the outer angle bar, the said hub by preference having a square socket 21 to receive a key, whereby the cam is turned from the position shown in dotted to the position shown in full lines Fig. 3, and vice versa, the first-named adjustment of the cam disposing the apertures 16 out of alinement with the apertures 8, so as to prevent the entrance of air and the second reversing such relation of the parts.

22 indicates an angle shaped slide plate fitting in the passage formed by the angle bars and against arm 2 of the inner one and provided at its upper edge with a flange 23 underlying arm 3 and provided like the latter with. equi-spaced apertures 24 adapted to be thrown into or out of register with apertures 4, by a cam as described, and shown in Fig. 3, the slide plate 22 being provided with longitudinal slots 25 to receive angle brackets 3 the slots being sufliciently long to accommodate the slidable movement of plate 22. will thus be seen that the slide plates or valves for controlling the admission and exit of air to and from the passage between. the.

angle bars are capable of independentoperation. The advantage of this independent operation will hereinafter a pear, it being noticed in this connection t at air may be supplied to the passage, under pressure, through the medium of the supply pipe 26 communicating with a blower or equivalent sential respects to the outer angle bar 5-6 eiecept that the inwardly projecting flange 31 is provided with apertures 32 instead of having such apertures in the outer edge of bar 30, as would be the case if said bar corresponded inallres'pects to bar 5-6.

33 indicate screw bolts extending through bar 30 and brackets 34 secured to arm 29 at oneend andto arm 27 at the other, and 35 is a cushionsecured to each bracket 34 for receiving the pressure of the side edge of the window glass 7. 36 is a slide plate having slots 37, similar to slots 14 in plate 13, through which the screw bolts 33 (see Fig.

5) extend andfitting snugly betweenbar 30 and the nuts 38 engaging the screw bolts. TlllS slide bar is provided with an ap'ertured flange 39 to control the admission or exit of air through the said apertured flange 31.

40 is a slide bar corresponding to slide bar 22 and provided with slots 41, through which the brackets 34'project, and said slidebar is provided'with an 'apertured flan 'e 42 to cooperate with flange 28 in control the admission or exit of air through said apertured flanges. It will be noticed that the side portions of the window front con'struction rest upon the flanges 3 and 6 of the basesection, but that communication is established be tween the assage of the base section and that formed by and between the side sections through the space between the he es 3 and 6 beycne the outer edges of the win 0w glass as shown most clearly in Fig. 5. Only one side section is shown as they are of duplicate construction and the top section 43 is also of the same construction.

The side and top sections are equipped with means similar to those described and shown in 3 most clearly, for longitudinally adjusting their slide plates, it being noticed in this connection and by reference particularly to Fig. 4-, that the hubs oi the ntrics are provided with outwardly prolanges 44 "o prevent the cams being 'ng into the passages nee by their res active angle bars.

two window lights are disposedat Y i e to each other, It provide a division scams piece or mullion constructed as follows:45

gaging the inner ends of said bolts and nuts- 52 engaging the bolts in the passage formed by and between the said angle bars.

53 are apertured slide bars fitting against the inner sides of apertured flanges 46 and connected at intervals by angle brackets 5 l.

5 5 are independent apertured slide lates fitting against theinner sides of the ights and fitting snugly between the inner side of angle bar 48 and nuts 52. The slide lates 55 are provided with slots 56, one on y appearing, through which bolts 50 extend and are equipped with slots, not shown, correspondlng to slot 17 and are engaged by cams correspondin to cam 18 to be turned by a key 58 in or or that their apertures may be thrown into or out of register with the apertures of the angle bar 48, it being preferred that said c'amsshall be operated from the outside of the mullion and to accomplish this ur ose, bar 45 is preferably provided with eylioles 57 (one only of which appears) through which the key is inserted.

To vertically adjust the apertured slide plates 53, one of the brackets 54 is provided with a slot 59 corresponding to slot 17 and engaged by a cam 60 corres onding to cam 18 and adapted to be turned ythe same key,

if desired, that is used to operate the other cams referred to. By this-arrangement it will be seen that the apert'ured slide lates 55 are independently ad ustable and t at slide plates 53ers likewise simultaneously adjustable independent of slide lates 55. By having the various aperture slide plates of the base, side and top sections independently adustable it will be ap arent that the person in control can effect t e discharge of air either side sectlon or from one'or'more of said sections simultaneously. -He can thereforeconcentrate practically all of the air at any articular point on or around said Flight. f the entire glassis frosty pr-apt to become frosty he can discharge the air a ainst the light along the four edges. It W' thus be seen that I have provided means for dissipating frost or preventing its accumulation w the window light by the natural circu lation of the air and can stimulate or increase upon its circulation by closingflthe outside apertures and forcing air under pressure through pipe 536 or its equivalent, it being of course understood that-there may be a pipe or pipes stricted to the exact details of construction shown and described as obvious modifications will suggest themselves to one skilled in the art.

Having thus described the invention what I claim as new and desire to secure by Lettors Patent is:-

1. In a window front construction, a pair of barshaving apertures, a window light between said bars, and a slide plate fitting in the passage formed by andbetween the bars and adapted to cover or'expose the apertures of one of them.
